加热炉是钢铁、治金、机械、石油、玻璃、化工等工业部门广泛使用的加热设备,多以重油作为燃料,燃烧过程复杂。目前在工业生产中使用的加热炉大部份热效率低,能源消耗高,浪费大。在当今世界能源危机的情况下,采取必要的节约措施,已成为当前紧迫的任务。因此实现加热炉燃烧控制自动化受到特别重视。一、自动燃烧控制的任务 Heating furnace is a widely used heating equipment in the steel, metallurgy, machinery, petroleum, glass, chemical and other industrial sectors, mostly with heavy oil as fuel, the combustion process is complicated. At present, most of the heating furnaces used in industrial production have low thermal efficiency, high energy consumption and large waste. In the current energy crisis in the world, taking the necessary savings measures has become an urgent task now. Therefore, the realization of furnace combustion control automation paid special attention. First, the task of automatic combustion control
